His work is characterized by long intros, self-drawn illustrations for his songs’ videos, and generally long song length. His predominant genre is trance, although he has done songs in other genres as well. Despite being skilled in the musical area, he does not write his songs' lyrics himself, but instead asks for them on PIAPRO.
In the illustration area he is recognized for being the illustrator of the popular light novel Oreimo and is an animator for the studio BONES. His style is easily recognized thanks to his use of rounded features (mainly the eyes), clear lines, and colorful cel-shading.
